Removing the top cover: 2145-CG8 or 2145-CF8

You can remove the top cover of a SAN Volume Controller 2145-CG8 or 2145-CF8 node to access the node components.

Before you begin

Important: Before you turn on the node, replace the cover for proper cooling and airflow. Operating the node for extended periods of time (more than 30 minutes) with the cover removed might damage components.

1. Read the safety information to which Preparing to remove and replace parts refers.
2. Optional: Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power off the node.
   Most maintenance procedures that require you to remove the cover are performed with:

   • The node turned off
   • The power cables disconnected
   • The data cables connected

   Depending on the part that you are removing or replacing, you might be able to leave the power cords and the data cables connected. The removal or replacement procedure for each part describes what to do about power, the power cords, and the data cables.

   If you are removing or replacing a hot-swap fan, for example, you can leave the node turned on, the power cords connected, and the data cables connected. However, do not run the node for longer than thirty minutes without the cover. If you must take a longer time, turn off the node as directed in MAP 5350.

3. You must work from the front and slide the node out to remove the SAN Volume Controller 2145-CG8 or 2145-CF8 top cover.

   You can accomplish most service actions when the node is fully extended from the rack on its slide rails.

4. Remove the node from the rack and place it on a flat, static-protective surface. See Removing a node from a rack.
5. Press down firmly on the blue tab ( 2  in Figure 1) that secures the cover ( 1 ) and slide the cover toward the rear of the node until the cover disengages the chassis.
